MRI (magnetic resonance imaging)
Magnetic resonance imaging (MRI) is a type of medical imaging (radiology) test, that uses magnetic fields and radio waves to produce detailed, 3-dimensional images (pictures).
Doctors can use MRI to help diagnose and manage many health conditions.
MRI scanners and a computer produce images of the internal body structures, including the brain and spinal cord, bones and joints, the heart and blood vessels, breast tissue, and other internal organs.
An advantage of MRI is that, unlike X-rays and CT scans, it does not use ionising radiation. However, MRI scans are not always the preferred type or first choice of imaging.
